    for wmp and ie, the 32 bit version offers better compatibility w plugins but
    why the other apps?
    there are 2 versions of each app (in program files and program files x86)
    and it seems the default app launched is the x86 version

    WMP 64-bit
    If you want to use WMP64 for playing videos enconded in different formats,
    go to
    and download
    Install it and you will be able to play most videos
    There is also a "Vista Codec Package x64Components" v1.2.2 which is updated
    almost weekly.
    Look for it at

    IE 64-bit
    There is currently no Java, no Flash, no ActiveX support.
    Java support seems closer but it is not there yet.
    Eventually we will have it.

    thanks, i knew how to make ie and wmp use the x64 version by default :)
    i was just wondering why MS decided to launch the x86 versions of mail,
    calendar, photo gallery etc by default also hehe.

    my mistake.
    after looking at the shortcuts and the registry again, the default version
    of mail etc launched is the x64 version although the 32 bit version also
    exists in program files (x86)

  5. I think they chose which to make default based on backwards compatibility

    FYI - you can always tell which is running by checking task manager.
    The 32-bit versions always have "*32" after their name. The 64-bit
    ones will not.

    Must admit I don't know what ails you... I've had sciatica for about 8 weeks
    now. That, sciatica, sucks big time. Major pain. Point being... I know what
    it feels like to not feel well for extended periods. Man... it sucks. Sorry
    to hear you're having to endure not feeling well. Best of luck in that

    I would like to know also how do you make 64-bit default for everything or
    atleast IE 7

    Sorry, but you can't. You can go thru the registry and change any that are
    defaulted thru the registry, but for the most part any that are launched by
    a 32-bit program will be the 32-bit version of IE.

    alternative but for life of me cant remember it!!

    Well if you can remember the command to make all 64 bit apps default or tell
    me when I need to do in the registry to make IE 64 default, I would
    appreciate it.

    That command is only for Media Player 11. What about the command for
    Internet Explorer 7?
